Abstract (EN):
The main features of the methodology developed for the assessment of concrete bridges are described. The structural model is based on the finite element techniques using an elasto-visco plastic formulation to precise estimation of the response and the ultimate strength of concrete structures. The application of this methodology to a prestressed concrete viaduct is presented to appraise the computational code and to illustrate its applicability. This practical example allowed to evaluate the influence of the main design parameters for different load conditions and at different ages of the structure. The results obtained from the analyses were used to identify the most important parameters for each limit state studied, and the critical zones that should be carefully controlled to get a rational maintenance.
